"Bei't known that I, JOHN T. H. PAUL, a citizen of theUnited States, residing at Chicago, in the county'Of Cooki and State of IlllIlOiS, have'invented a new and lusef'ullmprovement in-Conveyers, Of which the follow.

' 1 mg is a specification.

My invention relates, particularly, to im-- .provements'm those parts of a conveyer which serve for transporting packages from a lower to a hi her plane, usually in a building, the generally-stated construction of such a conveyer involving a downwardly-inclined lower section deli-veringto the lower horizontal end of an upwardly-inclinedseption terminating at its upper. end in a horizontal portion whence the delivery of the packages takes place to a section of the conveyer on an up er floor or plane.

nthe accompanyin drawings, Figure 1 illustrates my improved veyer by a broken view in side elevation; 2is an enlar ed broken plan view of the inclined interme iate section, with one-half of the traveling slat-apron removed to avoid obstructing. details which should be shown;

Fig. 3,, a section taken at the line 3, on Fig. 2, andviewed in the direction of the'arrow, and Fig. 4, a section taken at the line 4, on Fig.3, and viewed in the direction of thearrow.

Interposed, .as usual, between a downwardly-inclined lower delivery-section 5 and the ordinary upper receiving section (not shown) of the conveyer, is theinclined section'6, involving an inclined portion terminating at its lower end in a horizontal portion 7 to meet the section, 5, and at its upper end in a horizontal portion 8 to meet the upper section, ,referredto, a of the conveyer. The frame9 of the intermediate section, which describes a curve, as shown, at its junction with the lower horizontal portion, may in volve any suitable or usual construction, be-

ing commonly co posed of up er and lower longitudinally extending .ang e-bars properl braced andtied together, the longituc ina members affording, in one way or another, confining guides for ,the endless traveling chains, carrying the package-propelling flights, as hereinafter described.

Adjacent to a wall 10, o'r'other' suitablesupportforthe upper-end 8 of the inclined.

section 6 is rigidly suspended from the frame 9 a platform ll calrying a motor 12, con-' construction of con ventionally represented as an electric motor. The motor has an endless-belt connection 13 INCL, OF CHICAGO,

witha pulley 14 on one end of a drive-shaft 15,- j ournaled in' the horizontal ortion 8 and connected at its opposite en 'by suitable gearing, partially shown in Fig. 1 at 16, with the sproOke't-canying' shaft 17 .joumaled on the end of the part 8 for driving that shaft.

and also a similar shaft 18 journaled at the end of the part 7, through the medium of endless chains 19 (shown dotted in Fig. 2)

connecting these two shafts at sprockets 20 and 21 respectively on their opposite ends, these chains extending confine 1 along the upper and lower side-members o the frame. In a pair of an le-bars 22and 23 su ported to extend lengt wise of the frame 9 lihtween its sides and from the end of the portion 8,

short of the curved portion of the section 9, are journaled rollers 24 to afford an anti friction way, or roller-portion of the section 6, for packages. At the lower end of this way is journaled in the frame 9 a shaft 25 carrying On one end a sprocket 26 having an endless-chain connection 27 with a simi-- lar sprocket 28 on the adjacent end of the shaft 18. Adjacent to the shaft 18 is journaled in the frame 9 a shaft 29-carrying on its ends similar sprockets 29 which are'connected with sprockets on the shaft 25 by endless chains 30 guided, like the chains 19, in channel-irons, as represented in Fig. 4, the chains 30 being connected at intervals by parallel slats 31 to form an endless trave1- ing apron, which is reinforced against sagging by a platform 32, preferably of sheet-' metal of the width of the aforesaid rollerway, and rigidly supported between the side members to conform to the'shape of the section 6 and to extend between said way and the sprockets 29 beneath the upper section of the traveling a ron, tances apartsay of four feet, moreor less, the chains 19 carry flights 33 for engaging the packages to be conveyed, asfhereinafter described.

At intervals along the shaft 18 are sewheels 34', which may be considered sootions of a drum; and on opposite sides of.

the upper art of the framework 35, which supports t e section'fi at its end-portion 7, are secured similar spring-arms 36, converging toward their forward free ends, be-

At siutable discured thereon to rotate with it, similar mg provided for the usual purpose of centering the packages in their movement upon the section 6.

, Y The conveyer-section is supported at'its its ends in the standards to pass through the slots in the heads, in which it carries eccentrics'40 ,to engage the heads, the'shaft being'provided upon one end with an operatin handle 41.

l ith the motor 12 in action, the flightchains 19 and the apron formed" with the slats 32 are continuously driven. The advance-package being conveyed (one form of which is indicated at 42 in Fig. 3, though my improved. device is adapted for conveying any of various forms of packages) on reaching the delivery-end of the conveyer-section 5, abuts against and is arrested by the wheels 34 until encountered by a flight 33. The first flight thus encountering the package in the travel of the chains 19 lifts its forward end over the wheels and clears that end.

The frictional contact of the forward end of the package with the wheels 34 it thus surmounts causes their rotation to carry the package toward the apron; and when the next succeeding flight encounters the rear end of the package it pushes the latter, advancing it upon the apron, the speed of travel of which'is the same as that of the flight-chains 19. Thus when a package becomes imposed upon the traveling-apron, while it is propelled by the pushing action of the flight it is carried by the apron, owing to the movement of the latter, without friction, as would ensue, were the apron stationary, to the detriment of the package. The flight sustains the package against back- Ward. slipping while it is riding up the inclined portion of the traveling apron and after it clears the latter to continue its progress over the rollers 24 to be delivered to the upper section of the conveyer to which the section 6 leads, as aforesaid.

An important feature of my improvement consists in the provision of the arresting members 34, particularly when the adjacent end of the conveyer section 5 is rendered vertically adjustable to cooperate with them,

since by the provision of the arresting-members the packages are properly spaced apart on the section 6 and are smoothly transferred thereto from the section 5; while the adj ustability of the last-named section adapts it to be raised to such a height with reference to the transfer-members 34 as to insure their transferring-action upon smaller packages and prevent the latter from being turned backward toward the sections 5 by engager ment or aflightJWit-h (Mines ends! As win be apparent, 'the arresting function of the Wheels 34 prevents more than one package at a time bein'glint roduced between flights upon the' s'e'ction'o'. This section 6, which is essentially an elevator, though shown inclined, would, if vertical, be within my invention.

What I claim as new and desire to secure by Letters Patent is i 1. In a conveyer, the combination with a 2.
